Automotive gear box has continuously variable gear separated from gear selection unit by fixed wall

摘要

An automotive gear has a housing, a drive shaft, and a continuously variable transmission (CVT) arrangement to change the gear ratios between the drive input shaft and drive output shaft. The CVT drives a mechanical gear with selector elements and a set of planetary gears. The infinitely variable gear (2) and mechanical gear (3) are separated from each other especially by a fixed wall (1) forming part of the housing.
